Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-fighting systems in smart buildings are complex, costly, and inefficient in managing fumes and integrating with other IT systems, leading to increased risk of intoxication and visibility issues during fires, while lacking flexibility and integration with the evolving infrastructure of smart buildings.
Innovation Solution
A multi-sensor device integrating various components like a clock, thermometer, air pressure sensor, microphone, accelerometer, CO2 and humidity sensors, and power supply, capable of transmitting data via radio and forming a mesh network for emergency communication, providing comprehensive environmental data for fire detection and integration with other smart building systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate fire-fighting subsystems are installed (detection sensors, signaling devices, extinguishing systems), then fire safety coverage is improved, but device complexity and installation invasiveness increase
Solution Approach 1:
The patent combines multiple fire-fighting subsystems (detection sensors, signaling devices, and extinguishing system controls) into a single integrated fire-fighting system. The housing contains all these components working together as one unified system, eliminating the need for separate installations while maintaining comprehensive fire safety coverage through the coordinated operation of integrated sensors, visual/audio alarms, and extinguishing mechanisms.
Solution Approach 2:
The fire-fighting system is designed as a multi-functional device that simultaneously performs detection, alarm signaling, and fire suppression control functions. The single system can detect fire conditions through integrated sensors, activate visual and audio alarms, control extinguishing agents, and provide directional guidance via rotating light panels, replacing multiple specialized subsystems with one universal fire safety solution.
2Reliability
If traditional fire-fighting systems are installed with separate components, then fire detection and response capabilities are improved, but installation invasiveness and cost increase
Solution Approach 1:
The patent integrates detection sensors, signaling devices, and extinguishing system controls into a single housing unit that can be installed as one compact system. This merged design reduces installation invasiveness by eliminating the need for separate mounting of multiple components while maintaining comprehensive fire detection and response capabilities through the coordinated operation of integrated subsystems.
Solution Approach 2:
The fire-fighting system employs a nested structure where multiple functional components (sensors, alarms, control circuits, and extinguishing mechanisms) are housed within a single outer housing. This nesting arrangement allows all fire safety functions to be contained in one installable unit, reducing the invasive nature of installation while preserving full detection and response capabilities.
3Reliability
If comprehensive fire-fighting subsystems are deployed, then fire safety coverage is improved, but integration with smart building IT systems becomes more difficult
Solution Approach 1:
The integrated fire-fighting system incorporates standardized communication interfaces and data collection capabilities that enable seamless integration with smart building IT systems. By consolidating multiple functions (detection, alarm, suppression control) into one system with unified communication protocols, the patent simplifies integration compared to coordinating multiple separate subsystems, while maintaining comprehensive fire safety coverage.

AI summary
The general scope of this invention is the field of fire-fighting systems understood in a broad sense, and in particular fire-fighting systems in which very high levels of effectiveness are intended to be acieved, and which, therefore, tend to become systems of increasing complexity. This complexity substantially depends on the fact that the ways in which a fire originates can be different and numerous, and it is evident that the timeliness of detection is crucial in triggering effective reaction measures. Fire-fighting systems must therefore be prepared to make use of an increasing quantity of sensors, both in number and in type. In other words, a high-performance fire-fighting system must have a large number of sensors. The evolution of fire-fighting systems, like for of all systems, in general, must necessarily be framed in the wake of the so-called "smart buildings", that is highly computerized buildings, characterized by the presence of a multitude of systems, in which information acquired by each system are exploited to the benefit of the other systems as well. The intuition behind the present invention consists in having overturned the definition of the technical problem underlying the integration of the different systems that characterize the so-called "smart buildings", proposing not to start from the systems and then look for ways to integrate them, but starting from the sensors. The problem of integration was thus formulated by putting it in different terms: i.e. in the definition of a multi-sensor not specifically linked to a particular system or to a particular function, but suitable for collecting a wide variety of information, some of which not typical of the current systems installed in "smart buildings", but certainly useful in order to collect general information on the state of the "smart building", so as to activate any implementation functions of various types and nature, including the management the events related to fires.
